摘要
对聚丙烯纤维混凝土的力学性能、变形性能、抗裂性能及耐久性能进行了试验研究。结果表明 :在混凝土中掺入一定量的聚丙烯纤维是克服混凝土开裂的有效途径。纤维在混凝土中所形成的乱向支撑体系 ,产生一种有效的二级加强效果 ,能较大幅度地提高混凝土的抗裂性能 ,改善混凝土的抗渗性能。
The experimental research is conducted for mechanic property,deformation,crack resistance and durability of polypropylene fibre concrete.The result shows that certain quantity of polypropylene fibre mixed in concrete is the efficient way to avoid concrete crack.At the same time,the anti seepage property is improved.The influence machanism of polypropylene fibre on concrete crack resistarce is approached.
